Alex Shlyapnikov	6f1c26f222	[libFuzzer] Periodically purge allocator's quarantine to prolong fuzzing sessions. Summary: Fuzzing targets that allocate/deallocate a lot of memory tend to consume a lot of RSS when ASan quarantine is enabled. Purging quarantine between iterations and returning memory to OS keeps RSS down and should not reduce the quarantine effectiveness provided the fuzz target does not preserve state between iterations (in this case this feature can be turned off). Based on D39153. Reviewers: vitalybuka Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D39155 llvm-svn: 316382	2017-10-23 22:04:30 +00:00
George Karpenkov	10ab2ace13	Move libFuzzer to compiler_rt. Resulting library binaries will be named libclang_rt.fuzzer*, and will be placed in Clang toolchain, allowing redistribution. Differential Revision: https://reviews.llvm.org/D36908 llvm-svn: 311407	2017-08-21 23:25:50 +00:00

[libFuzzer] Periodically purge allocator's quarantine to prolong fuzzing sessions.

Summary:
Fuzzing targets that allocate/deallocate a lot of memory tend to consume
a lot of RSS when ASan quarantine is enabled. Purging quarantine between
iterations and returning memory to OS keeps RSS down and should not
reduce the quarantine effectiveness provided the fuzz target does not
preserve state between iterations (in this case this feature can be turned off).

Based on D39153.
